3.4 TXD Input

The TXD input pin is how messages are transmitted to the bus through the transceiver. TXD can be accessed using the main digital IO jumper. There is an optional pull-up resistor for this signal that may be populated to bias the pin state when the transceiver is not active. There is also a footprint for a filter capacitor if desired by the user.
